Events
When I woke up just after dawn on September 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer…but I suppose that was exactly what I did
Alexander Fleming (1881–1955)
Fleming discovered the inhibitory effect of the Penicillium mold on his staphylococci culture plate after returning from holiday on September 3, 1928. He named the substance “penicillin” on March 7, 1929, and published his findings later that year.
